how do i synchronize my subscribtion


Hi,
I'm not sure what's the subscription service to which you are subscribed. However I've given you the steps below. Try whatever suits for you.
This error typically occurs when the DRM licensed files have expired. 

SOLUTION 1 - Songs ripped from an audio CD 
If the songs were ripped from a CD using Windows Media Player, modify the Rip Music settings


SOLUTION 2 - Songs downloaded from music subscription service 
If the songs were downloaded from a music subscription service (e.g., Napster, Rhapsody, Best Buy music store, etc.), follow these steps:  
1. Make sure that your account subscription is updated and active. 
2. Put the device in MTP mode and connect to the computer, then log in to your music subscription account. 
3. Renew the licenses of your tracks 
For Rhapsody: 
On the Rhapsody console, right-click on your device and select License 
 

1. Check the date & time on your PC & on your mp3 player. They should be one and the same. 2. You need to synchronize your device with rhapsody once in every 30 days. It's a must. Failing to do so, you will not be able to play music in your mp3 player. Here are a few a steps to synchronize your device with rhapsody: 1.Open Rhapsody / Best Buy Digital Music Store and sign in 2.Connect your mp3 player to the computer 3.Go to My Account --> Update Track Licenses 4.Transfer a track to your device 5.Disconnect your device and enjoy music on the go!
3. Here is a link to get the Sansa Firmware updater to update the firmware for your device automatically: http://www.sandisk.com/Retail/Default.aspx?CatID=1376 
4. Click on this links if you are asked to synchronize your device with rhapsody? http://reclisten.custhelp.com/cgi-bin/reclisten.cfg/php/enduser/std_adp.php?p_faqid=6606&tabName=tab3 

For others: 
Contact music subscriber for instructions on how to renew as they vary.

SOLUTION 3 - Rename the Windows DRM folder 

NOTE:  The Windows DRM (Digital Rights Management) folder contains licenses for secure media files such as your subscription tracks. 

STEP 1 - Edit the folder options of the PC to show the hidden files      
Windows XP: 
1. Double-click My Computer
2. On the Menu bar, click Tools > Folder Options, and then click the View tab. 
3. Under Hidden files and Folder, click to select Show hidden files and folders
4. Under Hidden files and Folder, click to clear Hide protected operating system files (Recommended) check box. 
5. Click Apply, and then OK

Windows Vista: 
1. Double-click Computer
2. Click the Organize button at the upper left corner. 
3. Click Folder and Search options. 
4. Click the View tab and select Show hidden files and folders
5. Click to clear the Hide protected operating system files check box. 
6. Click Apply, and then OK

STEP 2 - Rename the DRM folder

You can get the files from an online music service like iTunes, Napster, Rhapsody, Limewire, Bearshare, etc. Or you can use Windows Media Player 10 or 11 to "Rip" songs from a CD - I would reccommend ripping them in mp3 format.

sync music to continue listening...


first you must format the player using msc mode then after that retransfer the songs to the player. If you are receiving this message it means that the songs on the player have expired. This is normal if you download the songs off rhapsody, napster or any online music stores and if you have ripped songs iwht copy protect music on it if you ripped them using windows media player 10.

If you have ripped the songs using windows media player 9 then you may want to rerip then again using windows media player 10 ( provided that you disable Copy Protect Music in The RIP tab ) and windows media player 11. If the songs came from music stores (napster,Rhapsody etc.. ) you can resync them using their software. You may want to reformat your player then retransfer the songs. This is normal if you purchase the songs. It dont mean the player is faulry its just the songs.
